Hi Heidi, my dd has never been much of a sleeper to start with and does not go through the night without a feed. She did used to settle after her 4ish feed though and like your dd hasn't been lately. On the plus side she is back in bed for a nap by 7 and up in time to take ds where he needs to go. I am personally putting it down to teething and going with the flow. I feed her as that comforts her and I much more likely to settle her that way but I wait until she asks for it iykwim. Could teeth be the issue for your dd? How do you settle her down at night, could you mimic this at 4.30?

touch would my dc's haven't had this prooblem, much, so i'm not recommending anything from experience (and my brothers dc's can every now and again still make at 5! and they are six!! she has a very clean house! )

there is that metthod where a about an hour or two (someone will probably know more about this than me) you wake them up. Not wide awake, but rouse them out of deep sleep then let them go back to sleep, and by interrupting the deep sleep it means they have gone 'back' in to deep sleep when the would usually wake up. so, it means you waking up but this would be more like the middle of the night and hopefully for about ten mins?

maybe try a little later bedtime. It is just probably down to teething so put some anbesol on her gums when she wakes, then go through what you do at bedtime. I wouldnt suggest waking her to interupt her deep sleep though. Never wake a sleeping baby

You have my total sympathy it is truly soul destroying. Can you tell us a little bit about her daytime sleep/ routine. I have struggled with ds early morinings for 5 years..is a bit better now (usually makes it to after 6)
